IMPROVEMENT IN RING SPINNING-FRAMES AND TWISTERS.

Specification forming part of Letters Patent No. 180.144. dated uly 25,1876; application filed September 30, 1874.

. forming part of this specification, in which Figure I shows myimproved spinning-machine, having a fixed and stationary but yetadjustable ring, and a reciprocating livespindle. Fig. II is a sectionalelevation through the center ofthe spindle, showing the bolsters, step,and the driving-whirl all in section. Fig. III shows the whirl and thesplines, which enter the grooves in the spindle, and by which rotativemotion is imparted to the spindle. Fig. IV is a top view of theadjustable hinged ring. Fig. V is a top view, a side view, and

an enlarged section of the oiling-tube M.

The nature of the first part of my invention consists in so constructingthe spindle for a ring spinning-frame that the same may be removed forcleaning without taking the band oftthe whirl, and that the spindleshall be equally well adapted for spinning or twisting frames havingeither stationary or reciprocating rings.

The second part of my invention relates to.

the application of a stationary ring to twisting-frames in whichtwo ormore threads are twisted together.

In the drawings, a is the spindle, which is supported in the step-railO, and held to the said step-rail O by the hook N, so that whenreciprocating motion is imparted to the steprail the spindle willreciprocate with it. The

whirl K rests in and is supported by the bolster secured to the rail It,in which it freely revolves. The spindle a passes through the whirl Kand the tube 1, made in one piece with the whirl K. The spindle has twogrooves made in the same, and the tube 1 has two splines or feathers,which enter into the grooves in the spindle, so that when rotary motionis imparted to the whirl K the whirl and the spindle will revolvetogether, while the spindle may be also reciprocating vertically.Secured to the rail P is the bolster i, the upper part of which forms anoil-cup, which is closed by a cap, h. Surrounding the spindle, andextending into the oil-cup, is a bolster-tube, firmly secured to thebolster i, the interior of which, forming the bearing for the spindle a,is lubricated by means of wicks secured to the conical tube M, so thatone end of each wick shall be at all times immersed in the oil in theoil-cup, while the other end extends to the spindle a above thebolster-tube, and so supply the oil to the bearing ofthe spindle. Abovethe oil-cup the spindle is enlarged, so as to form the projecting rim ortable g, from which one or more pins or teuons project, so that a bobbinhaving corresponding holes in its base will rest firmly, and revolvewith the spindle a, being held in a true vertical position by the bladeof the spindle, which extends into the bobbin. The ring I) is secured tothe bracket 0, which again is secured to the block E bya hinge, so thatwhen the block-piece E is secured to the rail X by the screwfthe ring,being a stationary fixture, may still be lifted sufficiently to allowthe operative to find any broken end on the bobbin and piece the same.The holes in the ringblock E and rail X are made larger than the.

screw f, so that the ring may be placed exactly concentric with thespindle, and firmly secured to the rail X. Theweightof the reciprocatingstep-rail is balanced by the weights T, secured to chains or hands S,and passing over pulleys or sheaves, so that when reciprocating motionis imparted to the step-rail, and by the same to the spindles, the samepower may be sufficient both to raise and lower the same;

The advantages of this arrangement are, primarily, the applicatiouof alight spindle for spinning and twisting yarn or thread to a ring -framehaving a stationary ring, and in which reciprocating motion is imparted,to the spindle, so that the length of yarn being spun, or the length ofthreads to be twisted, may be at all times the same between the traveleron the ring and the delivery-roll or the guide-hooks, no matter on whichpart of the bobbin the same is being wound. This length being alwaysuniform, the length of the bow formed by the rapid rotation of thespindle, and the form or diameter of the same, will also be uniform,while the drag of the traveler, the tension, and twist will all beuniform, and at a certain speed a known quantity, so that absolutelyuniformly twisted thread can be manufactured, which is not the case withtwisting-machines in which all the above conditions constantly vary andto a large extent.

The spindle, as shown, may be used on a spinning or twisting framehaving reciprocating rings, as well as on frames having stationaryrings. In the first instance the spindle would be a stationary livespindle driven by the whirl K through the splines or feathers in thetube 1, whereas in the second instance, besides the' rotary motionimparted to the spindle by the whirl, reciprocating motion would be alsoimparted to the same by the reciprocation of the step-rail O. In eithercase the spindle may be removed and cleaned without taking the band offthe whirl K by releasing the hook N. The whirl K and tube I may beraised sufliciently for oiling without removing the band. The twobolsters secured 10 the rails P and R can be easily adjusted so that thespindle will run with little friction by having the same fit loosely inthe rail, and secured to the same by screws passing through holes largerthan the screws, and which secure the bolster to the top of the rail, asis shown in Fig. I.

ISOJ I L In a spinning as well as twisting machine the ring must beabsolutely concentric with the spindle, and by making the ringadjustableand securing each ring to the rail X separately the same canbe placed absolutely true. The object of the hinge is to allow theoperative to raise the same just sufficiently to find a broken end, soas to avoid loss of time when a cop isspun; The lifting of the ringgreatly facilitates the operation of piecing. When a cop is to be spunon this spindle, the projection or table g is not required; butotherwise the spindle is made in all respects as herein shown anddescribed.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. The combinationof the stationary adjustable and hinged ring-guard (J, supporting thespinning-ring, with the reciprocating live spindle 60, arranged tosupport the cop or bobbin and the non-reciprocating whirl, substantiallyas and for the purpose set forth.

2. The combination, with the reci nocating live spindle a, of thenon-reciprocating whirl K, provided with the sleeve Z and the bolster V,arranged to support the whirl, substantially as and for the purposedescribed.
